I don't think she usually needs to be saved? Or at least not "constantly". She's had Dahlia and Michitaka (that one epic 80's action guy) as backup, but those feel like it's more to cover her back than because Kay's in totally over her head. Skimming through, most prominent one seems to Michitaka fishing her out of a river after getting thrown in, and that one was basically a cliffhanger that got resolved immediately in the next chapter. This is the first time I recall her ending up in this kinda of position for an extended period of time.
She's still more badass than not. Just because she's not a one-woman show all the time doesn't make her weak or helpless.
